Description
Technical field
The utility model relates to a kind of mechanical transmission band, relates in particular to a kind of mechanokinetic flute profile V band that is used to transmit, and is mainly used in the equipment of some motor-driven vehicles.
Background technique
The used V carrying material of mechanical transmission mostly is natural rubber or neoprene at present, effective serviceability temperature scope of natural rubber is-20 ℃～80 ℃, effective serviceability temperature of neoprene is-20 ℃～100 ℃, surpass this temperature range, can descend significantly the working life of V band, as under 120 ℃ serviceability temperature, existing natural rubber or neoprene are that the V of material of main part is be no more than 30 hours working life; Under-40 ℃ serviceability temperature, this two classes belt all follows the string, and the life-span also only has about 10 hours.
Along with the expansion in the utilization field of V band, its operating temperature is also more and more harsher to the requirement of material.For example the temperature of motor car engine driving belt just often reaches 120 ℃ now, moment, high temperature can reach 150 ℃, and the temperature in winters such as south poles, Russia is all below-40 ℃, in these cases, it is often extremely short working life to apply to mechanically operated V band, often is forced to adopt the expensive complicated mechanical kinds of drive such as chain.
EPDM (Ethylene-Propylene-Diene Monomer, ethylene propylene diene rubber) though low temperature resistant preferably and resistance to high temperature are arranged, but drawbacks limit such as the tear strength of itself is poor, dynamic fatigue resistance is poor, poor in processability its in the driving belt industry, the particularly use of V band industry, how the EPDM cogged V-belt of development of new is an object that is worth research to satisfy real needs always.
The model utility content
Technical problem to be solved in the utility model be provide at the above-mentioned state of the art a kind of can be in-40 ℃～121 ℃ scopes can be normally the effective flute profile V of long-term work band.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of flute profile V band is characterized in that being provided with strength layer from comprising the top layer of cloth outside to inside successively, upholding layer, bonding layer and compression layer in the aforesaid bonding layer.
Further, described top layer of cloth is the canvas of employing through the polyester-cotton blend material of 90 ° or 120 ° longitude and latitude braidings, and is the latex or the rubber cement processing of ethylene-propylene diene copolymer through the main gel kind.Described canvas is earlier through resorcinol-formaldehyde (RFL) latex dipping, apply one deck and ethylene-propylene diene copolymer again the Ethylene Propylene Terpolymer viscose binder of excellent bonds effect is arranged, be the latex or the rubber cement of Ethylene Propylene Terpolymer in surface-coated one deck master glue kind afterwards, total coating layer thickness is 0.2mm.
Further, the cotton rope that described strength layer adopts polyester material to make, and process main gel kind is the latex processing of ethylene propylene diene rubber.Described cotton rope is earlier through the hardening agent dipping, pass through resorcinol-formaldehyde (RFL) latex dipping again, apply one deck and ethylene-propylene diene copolymer again the Ethylene Propylene Terpolymer viscose binder of excellent bonds effect is arranged, be the latex or the rubber cement of Ethylene Propylene Terpolymer in surface-coated one deck master glue kind afterwards, total coating layer thickness is 0.15mm.
Compared with prior art, advantage of the present utility model is: by the rational deployment of layer of structure, make the cold tolerance of product improve in conjunction with the concrete proportion of raw materials of each layer, simultaneously, every physical property also improves greatly, has guaranteed using of product reliable and stablely.
